Applications

The industrial applications of barium sulfate include the manufacture of cellophane and photographic papers, and use as a filler for linoleum, rubber, oil cloth, and polymeric fibers and resins. The inertness of barium sulfate to light and heat makes it very useful as a paint pigment. The use of barium sulfate as an adsorbant in protein isolation has been reported. Barium sulfate is also widely utilized in studies of X-ray contrast agents. A study of the use of barium sulfate in pellet formulations with microcrystalline cellulose has been described. In biomaterials research, barium sulfate has been utilized in the preparation of acrylic bone cements.
